Example for Monitoring the Network Through Remote Alarm Notification Emails

Example for Monitoring the Network Through Remote Alarm Notification Emails

This example illustrates how to monitor an enterprise campus network through remote alarm notification emails.

Applicable Products and Versions

V200R005C00 or later versions

Networking Requirements

A company's O&M engineer Jack is responsible for monitoring the campus network to ensure normal service operation. The campus network consists of the headquarters and three branches a (R&D Dept), b (Sales Dept) and c (Finance Dept).

To monitor the network status, Jack has the following requirements:

  • Jack has to process a large number of emails during daily maintenance and is unable to monitor current alarms all the time. As a result, Jack requires that he be able to monitor the network status while completing other works.
  • Because a large number of alarms are displayed in the current alarm list, it is difficult for Jack to identify important alarms. As a result, Jack requires that he receive valid alarms only.

Requirement Analysis

  • Jack has to process a large number of emails during daily maintenance and is unable to monitor current alarms or the topology all the time. The remote alarm notification function can be used to enable devices to report alarms to Jack through emails. In this way, Jack can know the network status while completing other work.
  • Jack requires that he receive only a limited number of valid alarms. Alarm reporting rules can be set, so that devices report only critical and major alarms to Jack.

Prerequisites

Procedure

  1. Jack receives an alarm notification email when he is working.

    The alarm email contains brief information about an alarm, for example, the device that triggers the alarm and the alarm name.

  2. Log in to eSight and access the Current Alarms page from the alarm board to view alarm details.

  3. Find the alarm on the Current Alarms page. Click next to the alarm to quickly switch to the physical topology.

    NOTE:

    If a large number of alarms exist on the Current Alarms page, it is difficult to locate the desired alarm. You can set Customize Filter Criteria to filter alarms.

  4. On the Physical Topology page, check the device status and the position of the device on the network. If the device color is red in the topology view, the alarm exists. Jack needs to release a warning to other management personnel of the device to inform that the device is faulty and the fault is being rectified.

    NOTE:

    If an alarm triggered by a device can be ignored, you can mask the alarm.

  5. Rectify the fault. If it is a simple and common alarm, rectify the fault based on maintenance experience. If it is a complex alarm, rectify the fault by referring to Handling Experience on the Current Alarms page.

  6. Verify alarms. On the alarm board, check whether the alarm is cleared.

  7. Acknowledge the alarm. After acknowledging an alarm, choose Choose Fault > Historical Alarms from the main menu to add the cleared alarm to the historical alarm library.

    NOTE:
    • The alarms that are cleared but not acknowledged are displayed in green in the alarm list.
    • Alarm acknowledgement aims to improve the maintenance efficiency by preventing multiple O&M personnel from processing the same alarm.

  8. Optional: Add alarm handling experiences. Add the troubleshooting roadmap or key procedure of a complex alarm to the alarm knowledge base, so that maintenance personnel can refer to knowledge in the future.

    1. Choose Fault > Historical Alarms from the main menu.
    2. In the Alarm Details dialog box, click the Handling Experience tab and record alarm handling experiences.

Verification

Check whether the alarm count in the alarm board on the home page is 0.

Summary and Suggestions

  • After an NE is deleted, the following changes occur:
    • Alarms triggered by the NE are moved from the current alarm list to the historical alarm library.
    • The status of masked alarms of the NE changes to cleared.
    • Alarms on the NE are removed from alarm mask rules and remote alarm notification rules.
  • The following figure shows the status changes of an alarm.
